European Space Agency (ESA) astronaut and Expedition 46 Flight Engineer Tim Peake (@astro_timpeake) photographed the Alps from orbit on Dec. 27, 2015 and later shared the image with his social media followers, writing, “There may not be much snow in the Alps this winter but they still look stunning from here! #Principia” To source
NASA’s Earth Observatory has tracked down images resembling all 26 letters of the English alphabet using only NASA satellite imagery and astronaut photography. In this image, the letter ‘Y’ is for yardangs, elongated landforms sculpted by erosion and similar to sand dunes, but instead comprised of sandstone or siltstone. To source
The striking feature in this image, acquired by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter on March 19, 2014, is a boulder-covered landslide along a canyon wall. Landslides occur when steep slopes fail, sending a mass of soil and rock to flow downhill, leaving behind a scarp at the top of the slope. To […]

Zinnia flowers are starting to grow in the International Space Station’s Veggie facility as part of the VEG-01 investigation. Veggie provides lighting and nutrient supply for plants in the form of a low-cost growth chamber and planting “pillows” to provide nutrients for the root system. To source
